We summarize the week's scientific breakthroughs every Thursday.
In 2018, over 350,000 excess heart disease deaths were linked to phthalates. More research is needed to fully understand the chemicals' effects.
Bulky molecules mimic some properties of PFAS without their long-lasting chemical bonds and could replace PFAS in some water-repelling applications.
A miso test on the International Space Station shows fermenting food is not only possible in space, it adds nuttier notes to the Japanese condiment.
Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.
Chemists identify a single molecule that naturally tiles in nonrepeating patterns, which could help build materials with novel electronic properties.
Mars may once have held enough water to fill oceans and form coastlines. The planet’s red dust contains water and likely formed in cold conditions.
Urban wildfires like LA’s make harmful chemicals from burning plastics and electronics that can make indoor air dangerous for months.
The nonplastic polymer cleaned up eyeliner and permanent marker and broke down into molecules related to sugar and amino acids.
Sheep that eat death camas plants record the toxic meal in their earwax, a goopy health data repository that researchers are increasingly exploring.
